Laravel 的集合 Collection简介Illuminate\Support\Collection 类提供了一个更具可读性的、更便于处理数组数据的封装。具体例子看下面的代码。我们使用了 collect 函数从数组中创建新的集合实例,对其中的每个元素运行 strtoupper 函数之后再移除所有的空元素:$...
创建集合 默认我们model查出来的就是集合,创建也很简单:辅助函数 collect 为给定数组返回一个新的 Illuminate\Support\Collection 实例$collection = collect([1, 2, 3]); map(), reject()使用辅助函数 collect 创建一个新的集合实例,为每一个元素运行 strtoupper 函数,然后移除所有空元素...
如果您不希望保留原始键,可以使用 values 方法重新索引它们。sliding()The sliding method returns a new collection of chunks representing a "sliding window" view of the items in the collection:$collection = collect([1, 2, 3, 4, 5]); $chunks = $collection->sliding(2); $chunks->toArray();...
$collection->contains(function ($value, $key) { return $value > 5; }); // falseThe contains method uses "loose" comparisons when checking item values, meaning a string with an integer value will be considered equal to an integer of the same value. Use the containsStrict method to filter...
This method will return the values in the original collection that are not present in the given collection:$collection = collect([1, 2, 3, 4, 5]); $diff = $collection->diff([2, 4, 6, 8]); $diff->all(); // [1, 3, 5]...
